Description
Technical Field
[0001] This utility model relates to the field of bag opening machines, and more specifically, to a bag opening machine edge pressing strip structure that prevents fabric displacement. Background Technology
[0002] The pocket opening machine is a specialized piece of equipment used in the garment and other industries for the automated processing of pockets. When in use, the fabric to be processed is placed on the fixed knife mechanism. After the machine is started, the small pressing frame mechanism presses the fabric and moves it to the laser port. After the opening is cut, it is moved to the bottom of the folding knife. The folding knife, together with the manganese steel base plate, realizes the folding and clamping of the fabric. The entire process is pressed by the edge pressing rubber strip to ensure that the fabric does not shift during the movement, cutting and folding process, thus ensuring the processing accuracy of the pocket.
[0003] However, current rubber strips are usually fixed to the long strip edge with multiple bolts, which makes disassembly and assembly time-consuming and laborious, thus reducing the efficiency of disassembly and assembly. At the same time, the rubber strips need to withstand the pressure of the small pressure frame mechanism repeatedly during operation, which causes elastic deformation and fatigue or wear, thus gradually reducing the elasticity. Therefore, in order to avoid affecting the clamping effect, they need to be replaced in time, which increases the cost of use and reduces the practicality of the device. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0033] Please see Figure 1 This utility model provides a bag opening machine edge pressing strip structure to prevent fabric displacement, including a bag opening machine body 1, two long pressing strips 2 are arranged opposite each other on one side of the bag opening machine body 1, two rotating shafts 3 are rotatably connected inside the long pressing strips 2, an installation component 4 is fixedly connected to one end of the two rotating shafts 3, a rubber strip 5 is fixedly connected inside the installation component 4, two snap-fit components 6 are arranged opposite each other inside the long pressing strips 2, the snap-fit components 6 snap-fit with the rotating shafts 3, and a pulling component 7 is fixedly connected to the top of the long pressing strips 2, the pulling component 7 is connected with the snap-fit components 6.
[0034] Please see Figures 1-2 and Figures 5-11 The mounting assembly 4 includes a U-shaped frame 41 fixedly connected to one end of the rotating shaft 3. A mounting plate 42 is provided on one side of the U-shaped frame 41, and an insert plate 43 is fixedly connected to one side of the mounting plate 42. The U-shaped frame 41 and the rubber strip 5 are both provided with slots 44. The insert plate 43 is connected to the slots 44. The U-shaped frame 41 and the insert plate 43 are fixedly connected by screws 45. The arrangement of the U-shaped frame 41, the mounting plate 42, the insert plate 43, the slots 44 and the screws 45 facilitates the replacement of the rubber strip 5 and improves maintenance efficiency.
[0035] Please see Figures 3-6 and Figures 8-11 The snap-fit assembly 6 includes a slot 61 that passes through the rotating shaft 3. Sliding rods 62 are slidably connected to both sides of the long strip pressing edge 2. The sliding rods 62 snap into the slot 61. A circular plate 63 is fixedly connected to the outer wall of the sliding rod 62. The circular plate 63 is slidably connected to the inner wall of the long strip pressing edge 2. A first spring 64 is fixedly connected to one side of the circular plate 63, and the other end of the first spring 64 is fixedly connected to the inner wall of the long strip pressing edge 2. The slot 61, sliding rods 62, circular plate 63 and first spring 64 can conveniently fix the position of the rotating shaft 3, prevent the rotating shaft 3 from rotating randomly, and ensure the stability of the rubber strip 5 during normal operation. At the same time, the elasticity of the first spring 64 improves the snap-fit effect.
[0036] In a specific configuration, the pulling component 7 includes a limiting groove 71 fixedly connected to the long strip pressing edge 2. Two limiting rods 72 are slidably connected to each other within the limiting groove 71. An inclined block 73 is fixedly connected to one side of each limiting rod 72. A through groove 74 is provided through the sliding rod 62. The limiting groove 71 and the through groove 74 are slidably connected. The inclined block 73 fits against the inner wall of the through groove 74. A push block 75 is fixedly connected to one end of each of the two limiting rods 72. Through the configuration of the limiting groove 71, limiting rods 72, inclined block 73, through groove 74, and push block 75, the sliding rod 62 can be easily disengaged from the slot 61, which facilitates the release of the locking state of the rotating shaft 3 and makes it easier to rotate the rotating shaft 3, thereby realizing the rotation of the rubber strip 5 and improving the convenience of maintenance.
[0037] In a specific configuration, a positioning block 8 is fixedly connected to the top of the inclined block 73. By fixing the positioning block 8 to the top of the inclined block 73, it is possible to prevent the inclined block 73 from sliding out of the through groove 74, thus facilitating positioning.
[0038] In the specific setting, a partition block 9 is fixedly connected in the limiting groove 71, and a second spring 91 is fixedly connected on both sides of the partition block 9. The other end of the second spring 91 is fixedly connected to the push block 75. The partition block 9 and the second spring 91 can facilitate the reset of the push block 75.
[0039] In the specific configuration, inclined surfaces 10 are provided on both sides of the rubber strip 5. By providing inclined surfaces 10 on both sides of the rubber strip 5, it is possible to easily and elastically compress fabrics of different thicknesses, thereby improving adaptability and edge pressing stability.
[0040] The working principle of the anti-fabric displacement sealing strip structure for a bag opening machine is as follows: When using the anti-fabric displacement sealing strip structure, the rubber strip 5 is fixedly connected to the rotating shaft 3 via the mounting component 4. During normal operation, the sliding rod 62 is engaged in the slot 61 of the rotating shaft 3 under the elastic force of the first spring 64, which can fix the position of the rotating shaft 3 and the rubber strip 5. During operation, the inclined surface 10 of the rubber strip 5 elastically presses the fabric to prevent displacement, and at the same time, it can easily and elastically press fabrics of different thicknesses, improving adaptability. When one side of the rubber strip 5 is fatigued or worn and it is necessary to switch the working surface, the two push blocks 75 are pushed at the same time, so that the two push blocks 75 are moved away from each other, causing the limit rod 72 to drive the inclined block 73 to move and stretch the second spring 91. The inclined block 73 slides in the through groove 74 of the sliding rod 62, pushing the sliding rod 62 and the sliding block 73 to move. The circular plate 63 moves upward. During the movement, the circular plate 63 compresses the first spring 64 until the slide rod 62 disengages from the slot 61, releasing the engagement with the rotating shaft 3. At this time, rotating the rotating shaft 3 drives the mounting assembly 4 and the rubber strip 5 to rotate. After switching to the other side, the push block 75 is released, the second spring 91 resets, driving the push block 75 to reset, the first spring 64 resets, and the slide rod 62 is driven to re-engage into the slot 61 to fix the rotating shaft 3. This facilitates quick maintenance, extends the replacement cycle, and reduces the cost of use. When the rubber strip 5 needs to be replaced, the screw 45 is removed, and the mounting plate 42 is pulled to move the insert plate 43, causing the insert plate 43 to slide out of the slot 44, making it easy to remove the old rubber strip 5. At this time, the insert plate 43 is inserted into the slot 44 of the new rubber strip 5, and then the screw 45 is used to fix the U-shaped frame 41 and the insert plate 43.
[0041] It should be noted that the specific model and specifications of the bag opening machine body 1 and the rubber strip 5 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.
[0042] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
